Subject: [PATCH] Simplify BoostButton: remove client-side keysend, pass pubkey
 to boltwall

Payment now happens server-side in boltwall. The button just POSTs
{ refid, amount, pubkey } and the api client handles L402 automatically.
Removes sphinx-bridge, isSphinx, and NEXT_PUBLIC_BOOST_PUBKEY.
Default boost amount changed from 5 to 10.
